FRANKLIN STOVE.

Specification of Letters Patent No. 5,965, dated December 12, 1848.

To all whom it may concern:

Be it known that I, NATHANIEL CRADIT, of Ripley, in the county of Brownand State of Ohio, have invented a new and useful Improvement in theFranklin Stove, of which the following is a full, clear, and exactdescription, reference being had to the annexed drawings of the same,making part of this specification, in which Figure 1 is a frontelevation; Fig. 2, a vertical section through the line a :0 of Fig.

l, and Fig. 3 is a plan of the draft and damper plate.

The same letters indicate the same parts, in all the figures.

The Franklin is generally considered one of the most pleasant andagreeable parlor stoves ever invented, but hithereto, it has beendeficient of any simple and convenientmeans whereby the draft of theflue and the radiation of heat from the fire back could readily begoverned as circumstances might requirefor instance, when a fire is justkindled or fresh fuel added to a fire already burning a greatlyincreased quantity of smoke is evolved and at such times the capacity ofthe fiue requires to be enlarged and the draft increased or the roomwill be filled with smoke, but when the fire has burnt clear and butlittle smoke and gaseous matter is generated the fire back should beexposed so as to radiate the heat freely into the room and the fluecontracted at the same time to prevent unnecessary consumption and wasteof fuel by lessening the draft. To accomplish these objects I haveconstructed a Franklin stove with a higher fire back than usual, andalso applied to it a combined draft and damper plate A Figs. 1 and 3this plate may be made either fiat or curved and on its endsare'projecting pieces or pins a, a, a',a to be inserted into guidegrooves 0 on either end of the stove to hold the plate in its place andon which -to slide it up and down, The plate is held in any requiredposition by resting the projections a a in any of the notches e in thefront edge of the vertical portion of the groove 0 the knob or loop Z)is to take hold of to raise and lower the plate. plate is raised so thatits lower edge is up to the dotted line 2' (Fig. 1.) it entirely closesthe orifice '(O) of the flue and stops the draft altogether; but whenthe plate is lowered to the position seen in Fig. 1 as indicated by theblack lines, then the orifice (O) at the bottom of the fine is open toits fullest extent and the draft of the chimney is at its maximum and atthe same time radiation from the fireback is wholly obstructed; thedraft plate may be placed in any position intermediate between theextremes just named to modify the draft as required, and ordinarily itwill be found, after the fire has begun to burn briskly that if theplate is raised about two thirds of the utmost height to which it can beraised, that the draft will be suflicient and the back will be exposedso that the heat will be thrown out into the room by radiation veryfreely.

What I claim as my invention and desire to secure by Letters Patent, is,

The combination of the draft and damper plate A with Franklin stovesprovided with a notched groove 0 to receive the same as herein setforth.

In testimony whereof I have hereunto signed my name this sixth day ofMarch When the
